Description

Technical Field

[0001] The utility model relates to the technical field of feed production equipment, in particular to a straw crushing and mixing device. Background Art

[0002] In the field of agricultural waste management, straw, a common biomass resource, has long been a focus of industry attention for its efficient processing and utilization. Traditional straw processing methods often suffer from low efficiency, uneven fragmentation, inconvenient feeding, and unstable equipment operation. These issues not only affect the subsequent utilization value of the straw, but also increase processing costs and time.

[0003] First, from the perspective of structural stability, traditional straw processing equipment often uses a relatively simple support structure, which leads to vibration and noise during operation. This not only shortens the equipment's service life but also increases the burden on operators. Furthermore, equipment instability can pose safety hazards, posing a threat to both personnel and equipment.

[0004] Secondly, when it comes to material input, traditional equipment often lacks convenient feeding designs, resulting in a cumbersome and inefficient feeding process. Furthermore, materials are prone to accumulation and blockage during the feeding process, further reducing processing efficiency.

[0005] Furthermore, crushing and mixing is a key factor affecting the quality of straw processing. Traditional equipment often suffers from uneven crushing and incomplete mixing during the crushing and mixing process, resulting in uneven quality of the processed straw material, making it difficult to meet the needs of subsequent utilization.

[0006] Finally, the overall operational efficiency and safety of the equipment also require urgent attention. Traditional equipment lacks real-time monitoring and fault warning capabilities, making it difficult to detect and address potential operational failures during operation, increasing the risk of equipment downtime. Furthermore, material accumulation and blockage within the crushing drum also severely impacts equipment efficiency. Utility Model Content

[0007] The utility model relates to straw crushing and mixing equipment, which aims to solve the problems existing in traditional equipment and improve the efficiency and quality of straw processing.

[0008] The first aspect of the utility model provides a straw crushing and mixing equipment, which specifically includes: a supporting base, a fixed frame, a motor, a crushing barrel control box, a feed tray, a material guide rack and a crushing and mixing wheel; the supporting base is an equilateral triangle plate structure, and the three corners of the top plane of the supporting base are respectively fixed vertically upward with support blocks, and the upper ends of the support blocks are connected with a fixed frame; the fixed frame is a vertical crushing barrel fixedly clamped and welded between the upper ends, and the open end of the crushing barrel faces upward; the motor is fixedly mounted at the center position of the bottom of the fixed frame; the crushing and mixing wheel is vertically rotatably installed at a position near the lower middle part of the inner cavity of the crushing barrel, and the lower end of the rotating shaft of the crushing and mixing wheel passes through the crushing barrel and is fixedly connected to the upper end of the rotating shaft of the motor; the material guide rack is vertically embedded in the inner cavity of the crushing barrel near the upper end; an extended feed tray is horizontally fixedly mounted at a position on one side of the upper end of the crushing barrel.

[0009] Optionally, the lower end of the crushing barrel is a conical structure that is wide at the top and narrow at the bottom, and the lowermost end of the crushing barrel is fixedly connected to an inclined discharge pipe outward and downward.

[0010] Optionally, the material guide rack has a structure that is wide at the top and narrow at the bottom, and the main body of the material guide rack is a grid-like structure composed of connecting rods with even intervals.

[0011] Optionally, the bottom surface of the feed tray groove at one end away from the crushing barrel is higher than that at one end close to the crushing barrel.

[0012] Optionally, the upper end of the crushing and mixing wheel is located in the inner cavity at the lower end of the material guide frame, and the upper end of the crushing and mixing wheel is a six-blade-shaped chopping knife;

[0013] The middle part of the crushing and mixing wheel is a cage-like structure consisting of twelve twisted crushing knives, which is narrow at the top and wide at the bottom.

[0014] The lower end ring edge of the crushing and mixing wheel is provided with bent blades distributed in a ring along the side wall of the inner cavity of the crushing barrel, and the blade surface of the blade is a twisted structure.

[0015] The utility model provides a straw crushing and mixing device, which has the following beneficial effects:

[0016] First, the stability of the equipment structure has been significantly improved. The equilateral triangle design of the support base and the secure connection to the fixed frame through the support block ensure that the equipment maintains a stable posture during operation, effectively reducing vibration and noise, and extending the service life of the equipment.

[0017] Secondly, the convenience and efficiency of material feeding have been optimized. The design of the feed tray allows the material to slide naturally toward the open end of the crushing barrel, simplifying the feeding process and improving feeding efficiency. Furthermore, the tilted design of the feed tray prevents material accumulation and blockage during the feeding process, ensuring smooth material entry into the crushing barrel.

[0018] Furthermore, the crushing and mixing effects are significantly improved. The grid-like structure of the guide frame effectively guides the dispersion and guidance of materials before crushing, ensuring that the materials are evenly distributed around the crushing and mixing wheel. This design not only improves the operating efficiency of the crushing and mixing wheel, but also avoids uneven distribution and blockage of materials during the crushing process. At the same time, the multi-layered blade design of the crushing and mixing wheel fully considers the requirements of crushing efficiency and mixing uniformity. It can quickly chop large lumps of material into smaller particles, and further crush and refine the materials through the mutual interlacing and shearing force during the rotation process, ultimately achieving uniform mixing of the materials.

[0019] Finally, the overall operational efficiency and safety of the equipment are guaranteed. The real-time monitoring function of the control box ensures safe and stable operation of the equipment, promptly identifying and addressing potential operational failures. Furthermore, the tapered structure at the bottom of the crushing barrel and the inclined discharge pipe design allow for smooth material discharge, preventing accumulation and blockage within the crushing barrel, further improving the equipment's operational efficiency.

[0020] In summary, this straw crushing and mixing equipment achieves efficient crushing and uniform mixing of materials through its unique design and structural optimization, while improving the operating efficiency and safety of the equipment, providing a more convenient and efficient solution for the processing of straw and other materials.

[0031] Example 1: Please refer to Figures 1 to 4 :

[0032] The utility model proposes a straw crushing and mixing equipment, comprising: a support base 1, a fixed frame 2, a motor 3, a crushing barrel 4 control box 5, a feed tray 6, a material guide frame 7 and a crushing and mixing wheel 8; the support base 1 is an equilateral triangular plate structure, and the three corners of the top plane of the support base 1 are respectively fixed with support base blocks 101 vertically upward, and the upper ends of the support base blocks 101 are connected with a fixed frame 2; the fixed frame 2 is fixedly clamped and welded with a vertical crushing barrel 4 between the upper ends, and the open end of the crushing barrel 4 faces upward; the motor 3 is fixedly mounted at the center of the bottom of the fixed frame 2; the position of the lower middle part of the inner cavity of the crushing barrel 4 is vertically fixed. A crushing and mixing wheel 8 is installed to rotate, and the lower end of the rotating shaft of the crushing and mixing wheel 8 passes through the crushing barrel 4 and is fixedly connected to the upper end of the rotating shaft of the motor 3; a material guide rack 7 is vertically embedded in the inner cavity of the crushing barrel 4 near the upper end; an extended feed tray 6 is fixedly installed horizontally on one side of the upper end of the crushing barrel 4, and the lower end of the crushing barrel 4 is a conical structure that is wide at the top and narrow at the bottom. An inclined discharge pipe 401 is fixedly connected to the bottom outward of the lowest end of the crushing barrel 4, and the material guide rack 7 is a structure that is wide at the top and narrow at the bottom. The main body of the material guide rack 7 is a grid-like structure composed of evenly spaced connecting rods 701, and the bottom surface of the feed tray 6 groove is higher at the end away from the crushing barrel 4 than at the end close to the crushing barrel 4.

[0033] Example 2. On the basis of Example 1, the upper end of the crushing and mixing wheel 8 is located in the inner cavity at the lower end of the guide frame 7, and the upper end of the crushing and mixing wheel 8 is a six-blade-shaped chopping knife 802; the middle part of the crushing and mixing wheel 8 is a cage-like structure composed of twelve twisted crushing knives 801, which is narrow at the top and wide at the bottom; at the ring edge of the lower end of the crushing and mixing wheel 8, there are bent blades 803 distributed in a ring along the side wall of the inner cavity of the crushing barrel 4, and the blade surface of the blade 803 is a twisted structure.

[0034] The working principle of this embodiment is as follows:

[0035] The equipment is initially built on a support base 1, designed as an equilateral triangle. Vertically extending support blocks 101 at the three corners firmly support the entire unit. The upper ends of the support blocks 101 are connected to a fixed frame 2, which not only stabilizes the equipment but also serves as the mounting base for the crushing drum 4. The crushing drum 4 is securely clamped between the fixed frames 2, with its open end facing upward to facilitate material loading.

[0036] Motor 3 is fixed at the bottom center of fixed frame 2, and its power is transmitted to crushing and mixing wheel 8 through the rotating shaft. Crushing and mixing wheel 8 is installed vertically in the lower center of the inner cavity of crushing barrel 4. The lower end of its rotating shaft passes through crushing barrel 4 and is fixedly connected to the upper end of the rotating shaft of motor 3, thus realizing the direct drive of the crushing and mixing wheel by the motor.

[0037] When the equipment starts working, straw and other materials are put into the crushing barrel 4 through the feeding tray 6. The design of the feeding tray 6 makes the bottom surface of the disc groove away from the crushing barrel 4 higher than the end close to the crushing barrel 4, which helps the material to slide naturally to the open end of the crushing barrel under the action of gravity.

[0038] Material entering the crushing barrel 4 first encounters the guide rack 7. Located near the upper end of the crushing barrel, the guide rack 7 features a wide-top, narrow-bottom structure and a grid-like structure composed of evenly spaced connecting rods 701. This helps disperse and guide the material before crushing, ensuring that it is evenly distributed around the crushing and mixing wheel 8. This facilitates the orderly insertion of longer straw from a vertical position and its gradual comminution and cutting by the crushing and mixing wheel 8, preventing the straw from flying around and affecting the crushing efficiency.

[0039] Afterwards, the material enters the range of action of the crushing and mixing wheel 8. The design of the crushing and mixing wheel 8 fully takes into account the requirements of crushing efficiency and mixing uniformity. Its upper end is a six-blade-shaped chopping knife 802, which can quickly chop large pieces of material into smaller particles. The middle part is composed of twelve twisted crushing knives 801, forming a cage-like structure that is narrow at the top and wide at the bottom. These crushing knives are intertwined with each other during the rotation process to further crush and refine the material. The bent blades 803 distributed in a ring along the inner side wall of the crushing barrel 4 at the lower end ring edge have a twisted blade surface that can generate shear force during rotation, further crushing the material and promoting mixing.

[0040] After repeated crushing and mixing by the crushing and mixing wheel 8, the material is refined and evenly mixed. Finally, the processed material is collected by the conical structure at the lower end of the crushing barrel 4 and smoothly discharged through the inclined discharge pipe 401 for use in subsequent processes. Throughout this process, the control box 5 monitors the equipment's operating status to ensure safe and stable operation.
